33kV Live Tension Insulator Replacement
Вставка
- Опубліковано 23 чер 2015
- 33kV tension insulators are replaced by linemen working in Ceylon Electricity Board, at Kurunegala, Sri Lanka using insulator cradle and hot-sticks without interrupting power.
The method shown in the video is called Hot Stick method introduced in US in early 1910s with wooden sticks. Since this is live 33 kV potential, class 04 protection gloves with over gloves are normally required. However usage of Hotstick while keeping minimum safety distance from the live parts eliminates the requirement for bulky and difficult to handle insulated gloves. Therefore gloves are not used.
The people that do this kind of work are a special breed. The average consumer has no idea that these guys are playing an intimate game with death. Respect.
The average consumer has no idea what goes on beyond their consumer unit! Build absolutely nothing any where near me but just you make sure that I have electricity whenever I want it 😂
Wow. What a job to replace one insulator. Lots of practice to get each step just right. No room for mistakes. Well done.
I was nervous just watching them, total respect for anyone working like this .
That was amazing, those guys were so calm. Just one bad move and its a trip to the funeral director! Even the cameraman had a steady hand.
I am sorry but it takes a man with nerves of steel to work in that environment. Nothing but respect, but count me out.
Thank God things went well. May God protect the men who keep the lights on.
I’m impressed, most videos of linemen from pacific rim countries don’t wear shoes.
Much respect to these Linesmen who are having to work under difficult conditions and without some of the more sophisticated equipment available to others. I sincerely hope those insulating poles get regular dielectric testing for safety back at base. Just over two foot seems remarkably close to be working with 33kV. Thanks for posting your video.
Hassan Burrows they are using appropriate equipment. also, working outside their LOA (limits of approach).
Proud to see a detail video like this from Sri Lanka Superb (y)
What a hard work.. hatsoff to the team.. who doing live tower maintenance
"So boss, what about mistakes?"
"Mistakes?"
"Yes, like what you do or who you call ? "
"Well, family I guess..."
I do it using crane , manlift and come along to take the cable tension off. But you guys are awesome.
These guys were working like a well oiled machine, no yak-yak-yak, just a quiet respect for the power they were working with.
thanks for your comment.

That isn't the kind of job where you want to bullshitting around or has somebody there who is. One wrong move
can be your last if one is careless

Well, rbagel55, the lines are obviously grounded. Unless they wanted their rope to electrocute them.
Fascinating to watch that. Quiet, calm & so respectful of each other & the live lines they are on. I do not know why there are silly comments on gloves, as they can get in the way sometimes, esp: in a hot climate. Cannot wear rubber gloves in that heat! I once saw a line man in the hospital I was at up north of England, with his whole right arm & some of his right leg missing, with severe burns down his body. He'd been zapped by 33kv working near the electric railway lines. He thinks that fact is arm vapourized saved his life. He was in good typical Geordie spirits about it. Wow. Great respect for those men who do this.
Thanks for your comments
Incredible team work, well orchestrated. Flelicitations.
Yes u could easily tell they worked well together especially because there was very little talking. They were in sync.
wow , we fear from 220 v but they are working at such a high voltages with such peace, salute man

How do you get 220
Great job, Great crew and video editing.
Thank you, stay safe!
Such high quality Installation for 33kv.
In the US or Canada it would just be a half rotten wooden pole with some insulators strapped to it.
Good job lineworkers! I was imprerssed of your coordination and professionalism ! Good luck!
Never seen linesman work without insulation gloves before! Wow!
Pbbbbbt so what are those supposed to help you with maybe keep you from getting shocked LOL
No 33kV AC rated gloves. They can only make you clumsy and awfully hot. You will be dead if your hand gets closer than an inch to the line even with most safety gloves.
4 spacers probably 120kV. Probably it does not make much difference regarding gloves.
@@VagishaDas Each insulator is designed for 10 to15 kV each. This'll vary based on climate, humidity, pollution, and altitude. High in the mountains, you'll see 20% more discs on the lines up there. For example, below 7,000 ft or 1.75km altitude... 15kv distribution line has 2 discs, this 34.5kV line has 3 on vertical and 4 on the ends, where electical tensions are higher. A 69kV line has 4 to 5 hanging down plus 7 to 8 when used on end and turns. 115kV line has 7&9. 230kV has about 15 and 22, 500kv has 24 &30.
@@VagishaDasтут написано 33kV!!!
Very knowledgeable video..Respect to the people working there on top and to the team on ground..
Amazing! This is the real professional work that most people don't see everyday, great video 👍👍👍👍
Thanks 👍
Glowes for 120KV? I am not sure if there is any.
Looks like a text book change. Awesome job you guys have.
Salute all...bros
Thanks for sharing such a nice video that helps students to understand the installation of insulators. Keep posting such videos. Great job 👍
Thank you, I will
its a quick change but the stress of this 30min video is a beast, only who works with electrical lines knows the fear of be killed by a small mistake.
Very interesting and impressive / live life test performance ! Kudos to those young Inspectors !!
Thank you very much!
Все живы и здоровы. Работа выполнена отлично! Ура!
Да здравствуют ЭЛЕКТРИКИ!!!
👍👍👍👍
Excellent team work guys!
I realy feel very proud to them, if his team leader able to aware about flash/arc level for any type of fault oaccures during this type of job,
My suggestion to your company please provide them full body protection ARC SHUIT including (GLOVES, helmets with ARC Protection)to the technicians .
Calm, Quiet & systematic progress form starting of job to the successful completion !
Thanks
Прямо чётко, спокойно, с умиротворенностью. Залипательное видео.
Wow! That was awesome team work in Sri Lanka by those linesmen. Very dangerous and all in the name of zero power outage to their customers.
I really liked the video. Respect from India🇮🇳
Felicitaciones al equipo de trabajo, con la repetición de estas tareas se va perfeccionando la técnica. El señor en tierra vestido de blanco es el observador dedicado? convendría usar binoculares para no perderse detalles. Buen trabajo
Felicitaciones,creo que el riesgo vale la pena,trabaje un tiempo con cubas de rayos X y la verdad no me gusto mucho trabar con esos altos voltajes. mi respeto y consideración para Uds. hacen un buen equipo saludos.
Congratulations, I think the risk is worth it, work some time with x-ray tubes and the truth I did not like much to work with those high voltages, my respect and consideration for you make a good team greetings
I have such respect for these men ariund the world thank you seems so inadequate! Dang....😮
i wonder what happens to the old insulators once its taken down? there a lot of insulator collectors in the world that love insulators a lot, the popularity of insulator collecting is so big they have many websites dedicated to insulator collecting, i mean this community is huge! hats off to the work that these linemen do to keep the lights on and the stoves heated!
thanks for your comment
Que procedimiento tan bien sincronizado. Lo conocen al detalle. Máxima concentración. Buen trabajo.
thanks
TREMENDOUS Skill !!! That is what I call Teamwork . Great job guys, >

Amazing work by the lineman
great video! I would love to see more :)
Yes, this is "work under tension". There are basically 3 ways of this work: 1. "work at a distance" 2. "work in contact" 3. "work on potential". In this demo, distance work is done. For all types of work under voltage, precise technological procedures must be approved and a so-called "special mode of operation" must be arranged.
Very impressive job.Thumbs up to the linees.
Thank you very much!
That was incredible be safe.
Hats off to you 🙏great job and toughest job OMG 😱
how meny hats you have😆
27:01 I believe ol spot learned not to chew on my PC power cord anymore that's what I've been trying to tell you spot sometimes that snake bites back even when you bite the head off LOL excellent video excellent technicians
Awesome video, the end with the gifts raining down made me laugh
it is good team work the important that mean the worker fallow step by step until finished replacement it is very amazing
That was an amazing insight into what’s involved in live transmission line work. Neutralising a large bomb pales into insignificance in comparison to this work. I reckon that very dry weather conditions with minimum humidity is essential. Any dampness equates to a fatal conductivity path for the linemen. Continuing safe work to these men.
Thanks for commenting.
All my respect for them
Felicidades, son un gran equipo
I am an electrical engineer...I salute u all
Looks like a place where humidity is 110% and not one of them broke a sweat.
GOOD TEAM WORK DONE GUYS....
Parabéns pra essa equipe ecepcional
What happens if they drop one of those bolts or W pins?.... And how would they re-insert and re-start them?
Great job with safe work pattern, want to know how much time it takes to change one insulator .
Intéressant, j'aimerais être avec vous dans ces moments de travail pratique pour améliorer mes compétences
Very skilled tradesman!
great work!
Super fachowcy i takie wykonanie w PPN
My late father was an electrician. I used to watch him climbing into electric pole with a special shoes on to fix something and my heart was dropping out of my chest. I was so afraid even to go under high voltage power lines ,especialy in stormy weather, when they are making 'fireworks', nevermind to climb on it. Used to count how many cables still on the towers before crossing them in very fast run. Road to my school was crossing triple high voltage power lines and I've been told not to go any closer if any cable is broken and on the ground. Before I learned to read I knew that broken down power cable can kill from distance,when it reaches soil. My childhood worst nightmare:)
I can feel your concerns, but we know that without a map, without a compass and even without knowing what's the destination, human voyaged thousand of miles on unending sea thousand years ago. That's how we built the civilizations. We have to take the risks, main priority is that those risks shall be evaluated and appropriate measures shall always be taken to prevent them happening.
Brave man like it
Solute your team!!!!! 🙏💪
Love the fizzing noises as bits of the equipment charge and discharge. Not work for those of a nervous disposition. 😮
May you always be given health, greetings from Indonesia..
Thanks
Well done!
What is this antenna on ground?
men with brave hartz..
respect..
Works the lineman under Current?
Good work guys.
interesante la actividad saludos desde colombia
Veryy hard work....
Hat's of to electrical engineers
good job boss.
salute for work
c est tres beau de les voir travailler
Thanks.
THANKS BE SAFE ALL THE TIME
Excellent job
Is the safety yellow hat really necessary?
It looks like the insulator (old) was rusted at a long time ago. Do you know what happens when electricity and rust mix together? First, interference. Second, which was caused by the first effect, since there is an interference, all the electric from the high-voltage line will store in to the rust. Last but not least, blackouts.
Por qué cambian esos aisladores?
ගොඩක් වටිනවා..❤️
Very good they know what they do.
Sir why orange coller boll puting tranmision line
this job was for the real man only. if you have no fear in heights you're in
The height they were at was the least of their worries.
great video for sure
I use to test hot sticks that look like those they used. I never knew how to use them.
was it live work ?
Cool! Yeah working on live lines really isn't as dangerous as people would think, as long as you follow all the steps and precautions and don't try to show off and don't lose focus. I've heard it can get uncomfortable at higher voltages though, if you don't have a hot-suit. The electricity corona discharging off of you feels like needles poking your skin, (or so I've heard) and the 50 or 60 hz vibration runs through you.
Thanks for your comment, Corona is mostly present in Transmission lines, i.e above 66kV level.
Chaminda Herath : so you don't really feel any discomfort on line below that voltage then?
No As long as you are keeping recommended safety distance.
There is no doubt, but such constant “static” has long term health consequences for those amazing linemen.
@@noelkeane5603 yep. They are exposed to all the full strength emf so yeah, I’m sure you’re right
Será q a rede está desenergizada ?
Very professional.
Great job
Da li je to pod naponom
good job, good camera
I myself did the shooting. it was Nikon DSLR with limited other resources like editing software. Thanks for your feedback.
Nice job Guys

Very good video it's very Danger work
Amazing video! Very interesting, good camera angles, good editing, and great work by the line crew. How hot was the weather that day? For what looks like a tropical rain forest, the crew looked dressed pretty heavy in those jumpsuits. I hope they are well paid. They did a very professional job. How much does one of those 4-bell insulator chains weigh? Thanks for sharing. Stay safe!
Thanks a lot!
